2013 M3 V8 DCT oil change

[CorvetteConvert]

Anyone here changed the transmission oil on a 4.0 V8 M3?
What's the best oil to use and is it a lengthy job?
Thanks.

I went down to the local kebab shop and got a few litres of used oil from there.
Gear shifts were much smoother afterwards, though I do detect a hint of garlic when pressing on.

Nobody done this job?

These are the instructions off BMW TIS including the BMW Part numbers for the oil. I believe Pentosin make the oil :



- Connect diagnosis system and
start service functions (drive).
- Start engine (drive position N or
P)
- Record transmission temperature
using Tester
- (Drive position P)
- Permissible starting temperature
≤ 32 °C
- Idle speed: maintain at approx.
2000 rpm for 1 minute.
- Open fluid adjusting screw (1)
- Fill until fluid emerges
Max. transmission fluid
temperature 40 °C
- Insert screw

Also a DIY here :

Changing M-DCT Fluid

Important

Let your car cool for an extended period of time (at least 4 hours depending on the ambient temperature) before starting the process. If the transmission's temperature is too high, an incorrect amount of fluid could be added.

Fluid needed

83 22 0 440 214 BMW DCTF-1 (1L)
83 22 2 147 477 BMW DCTF-1 (20L)

Special tools needed

Fluid pump



Thermometer/contact pyrometer



Procedure

1. Remove the protective cover under the transmission.



2. Drain fluid by removing the plastic plug near the front passenger side of the transmission. Fluid can be extremely HOT! If your car was just driven, I would suggest waiting a few hours before draining the oil.

3. Once the fluid drain stops, reinstall the plug. Torque to the suggested value listed on the plug.

4. Open the filling hole (red box). Using a fluid pump, add M-DCT oil into the transmission. I added about 3 quarts before fluid started to emerge from the filling hole.



5. Ensure that M-DCT fluid inside the transmission is below 90 deg. F. Then, close the filling hole.

6. Turn on your engine. In position P, maintain 2000 rpm for about 1 minute.

7. Reopen the filling hole and add additional fluid (about 2 quarts) until fluid starts to leak out from the hole again. This process must be completed while the transmission fluid temperature is below 104 deg. F.

8. Close the filling hole and reinstall any removed panels.

Thanks, grateful for that.
